Origami structure on a box that includes the circuitry. To the bottom right of the box, the LED output that indicates the interaction between the user and the interactive origami.
My interactive origami is based on the physical response of a Venus flytrap when an insect touches the plant’s leaves. When an insect comes into contact with the leaves of a Venus flytrap, the leaves, similar in structure to a set of jaws, close and imprison the insect several seconds after contact.
The origami structure I used to represent the Venus flytrap is similar to the plant in that it is a structure that can open and close, similar to the plant’s leaves. To simulate the insect coming into contact with the plant’s leaves, the interactive origami uses touch as input to activate the closing of the origami structure (output). It uses a touch sensor, located at the very centre of the origami, and also uses LED output to indicate when the structure is not being touched, in the process of being touched, and when it will close and imprison whatever touched it. The structure is controlled by a servo motor that causes the structure to open and close.
Sketches of the conceptual and interactional mapping, as well as a possible idea to make the structure open and close using a servo motor.
Arduino code for the interactive origami:
int ledPinGreen = 13;
int ledPinYellow = 12;
int touchSensor = A0;
void setup() {
pinMode(ledPinGreen, OUTPUT);
pinMode(ledPinYellow, OUTPUT);
pinMode(touchSensor, INPUT);
}
void loop()
{
int val = digitalRead(touchSensor);
if(val == HIGH) {
digitalWrite(ledPinGreen, HIGH);
digitalWrite(ledPinYellow, LOW);
} else {
digitalWrite(ledPinGreen, LOW);
digitalWrite(ledPinYellow, HIGH);
delay(250);
digitalWrite(ledPinYellow, LOW);
delay(250);
digitalWrite(ledPinYellow, HIGH);
}
}
int ledPinGreen = 13;
int ledPinYellow = 12;
int touchSensor = A0;
void setup() {
pinMode(ledPinGreen, OUTPUT);
pinMode(ledPinYellow, OUTPUT);
pinMode(touchSensor, INPUT);
}
void loop()
{
int val = digitalRead(touchSensor);
if(val == HIGH) {
digitalWrite(ledPinGreen, HIGH);
digitalWrite(ledPinYellow, LOW);
} else {
digitalWrite(ledPinGreen, LOW);
digitalWrite(ledPinYellow, HIGH);
delay(250);
digitalWrite(ledPinYellow, LOW);
delay(250);
digitalWrite(ledPinYellow, HIGH);
}
}
